I used to get all my water from these Watermill Express vendors because they're everywhere and so convenient. I could always count on them being serviced daily. BUT now they no longer have a "date serviced" sticker. You have no idea what you're getting...I just as soon hook up to the hose in my back yard and take my chances. I tried to get in touch with the company months ago when I first went to one that had no date. I got nothing and nothing of any substance from an email. I'll go to every gas station, Walgreens or CVS looking for a good date on a machine than use these again.
